Quantitative measurement of the total, peroxyl radical-trapping antioxidant capability of human blood plasma by controlled peroxidation. The important contribution made by plasma proteins.
Plasma obtained from fasted humans has been analysed for total radical-trapping antioxidant content by subjecting it to controlled peroxidation using the thermal decomposition of water-soluble azobis (2-amidinopropane hydrochloride) at 37 degrees C to produce peroxyl radicals at a known, steady rate. It is found that the total radical-trapping antioxidant content is rather similar for the 7 sub...
متن کاملTHE DISTURBANCES IN IRON TRANSPORT AND STORES AND TOTAL FREE RADICAL TRAPPING ABILITY OF BLOOD PLASMA IN BABIES WITH MITOCHONDRIAL ENCEPHALO MYOPATHIES
Babies with mitochondrial encephalomyopathies had higher ferritin levels than controls. Although plasma iron levels were simi lar in both groups, babies with mitochondrial encephalomyopathies had lower transferrin levels. Thiobarbituric acid reactive substances in plasma of babies with mitochondrial encephalomyopathies were higher thun in controls suggesting increased lipid oxidation. We s...
متن کاملInfluence of malaria infection on peroxyl-radical trapping capacity in plasma from rural and urban Thai adults.
Measurement of peroxyl-radical trapping capacity (TRAP) were made in plasma from patients with malaria from a rural and an urban Thai community. The results were compared with those from control subjects living in the same areas and chosen to match the patients closely. Measurements were also made of various antioxidants including nutritional indices vitamin C and alpha-tocopherol and the non-n...
متن کاملTrapping of a tert-adamantyl peroxyl radical in the gas phase.
A bridgehead adamantyl peroxyl radical has been prepared and isolated in the gas phase by the reaction of a distonic radical anion with dioxygen in a quadrupole ion-trap mass spectrometer.
متن کاملPlasma Leptin Concentrations in Preterm Infants with Retinopathy of Prematurity (ROP)
Intruduction: This study was conducted to determine blood levels of leptin in premature infants with proliferative ROP.Retinopathy of prematurity (ROP) is a postnatal disorder of retinal vessels that develops in the incompletely vascularized retina of preterm infants. This disorder regresses in most patients but can lead to severe visual impairment. There is evidence that leptin stimulates angi...
